Salmon Falls Watershed

Horn Pond

This 227 acre lake lies south of Great East Lake and west of Wilson Lake with a small 1.8 square mile watershed. Horn Pond is fed by both springs and a few small streams, such as Horse Brook. The lake drains into the Salmon Falls River which forms a natural border between Maine and New Hampshire. The water quality of Horn Pond is considered to be good by Maine standards of clarity and nutrient levels and potentially non-supporting by NH standards based on the median nutrient levels. The potential for nuisance algal blooms on Horn Pond is low. Water flushes through Horn Pond 8.2 times/year, much more frequently than the average Maine or New Hampshire lake which flushes 1 to 1.5 times per year.
